Both the front and the back of the trays are playable. Each side features dimples for the balls (arranged in rows on one side and in an offset arrangement on the other side), resulting in virtually unlimited designing, positioning and building possibilities.

Because these little balls lend themselves especially well to being grasped by tweezers, the material to easily make one’s own set of tweezers is included. Grasping the balls with the tweezers adds a whole new level of fun and gives the mini-ball game an extra-special charm.
